Template parameters - is there a limit?

[Baz in Kent]

Hi, I’ve created a comprehensive template which shows all the desired parameters in red and ticked on the parameters page, however when I record them in a graph not all of them show up. Also when I view the template in the templates box I can’t scroll through it to see the parameters list, it jumps to the next template.
Is there a maximum number of parameters allowed in each template?

Cheers,
Baz
